It will never cure properly on concrete.

Can you put asphalt sealer over concrete.

Now this being said i wouldn t be afraid to try this on small area as a test. A concrete stain might hold up better. Asphalt can be successfully installed over concrete but due to the characteristics of each material you may not be happy with the long term results as the asphalt will ultimately crack in the same manner that concrete does. You can put asphalt over concrete but professionals don t advise it.

Concrete is a great base material because it is stable and allows for excellent compaction of the asphalt above. They do make sealers for concrete check with you hardware store or home center. Actually probably not a good idea. Asphalt sealers are specific chemical mixtures designed for asphalt penetration and top sealing.

In fact many miles of concrete roads are paved over with asphalt every year. Holes or cracks with depth of 2 inches or more require filling before concrete overlay is applied. It is designed to bond with asphalt. Before concrete installation begins the asphalt is inspected and repaired as needed.

Only work on 2 to 4 foot sections at a time. For most sealers pour out a line of sealant along the highest edge of the driveway. Use a squeegee or brush if needed to spread the sealant. Most asphalt sealers require a squeegee while most concrete sealers use a brush or sprayer.

No you cannot use blacktop sealer. When concrete deteriorates it draws and holds moisture. It will however require a little more maintenance than a typical asphalt overlay. I have a neighbor that has a concrete pad attached to his asphalt driveway.

It s hard to beat the aesthetic appeal of an asphalt blacktop driveway but over time the material can develop spider web cracks and low spots left. It looked good at first but within a year most of the sealer had worn off of the concrete. About 15 yrs ago when he resealed the asphalt he also applied the sealer to the concrete. The truth about asphalt over concrete an asphalt overlay is cheaper to install than replacing concrete and can provide a smooth ride over deteriorating concrete.

It is safe to pave asphalt over concrete. The asphalt is more porous than concrete which allows this application to work on asphalt.
